7 × (–3) × (–2)2 = ?

A. 84
B. 48
C. –84
D. –48

Answers

Answer 1

Answer:

7 × (-3) ×(-2)2 =

7 × -3 × -4 = (you have to eliminate all parenthesis in the equation.)

7 × -12 = -84

so your answer would be: C

Answer 2

Answer: 7*-3=-21 and -2*2=-4 so -21*-4= 84
answer is 84

Step-by-step explanation:

Elvia is job shadowing for an internship. She is required to complete at least 48 hours of shadowing in her chosen career. Elvia can shadow for 2 hours on weekdays and 6 hours on weekends. Which graph represents the number of weekdays and weekends that Elvia can shadow to meet her requirements? A.) Picture 1
B.) Picture 2
C.) Picture 3
D.) Picture 4

Answers

The graph that represents the number of weekdays and weekends that Elvia can shadow to meet her requirements is A. Picture 1

How to graph the requirements ?

To graph this inequality, we would typically draw the line representing the equation 2x + 6y = 48 and then shade the region that satisfies the inequality $2x + 6y \geq 48$ .

Since Elvia is required to complete "at least" 48 hours, the line on the graph will be solid, not dotted, to indicate that the hours represented by the line are included in the solutions that meet the requirements.

The point the graph would cross the x - axis is:

2 x + 6 ( 0 ) ≥ 48

x = 48 / 2

x = 24

The point the graph would cross the y - axis is:

2 ( 0 ) + 6 y ≥ 48

y = 48 / 6

y = 8

The correct graph is therefore Picture 1 which has the line as solid and the intercepts as x = 24 and y = 8 .

How many endpoints are needed to draw four line segments

Answers

If these four line segments are connected (kind of like a square) then only 4 endpoints are needed, but if they are all separate line segments, then you would need a maximum of 8 endpoints because any line segment has 2 endpoints and 4 line segments with 2 endpoints a piece equals 8 endpoints in total.

I hope this helped! :)

Final answer:

To draw four connecting line segments, you need five endpoints. This is because each line segment starts at one point and ends at another, with the end of one segment serving as the start of the next.

Explanation:

In mathematics, a line segment is a piece of a line that has two endpoints. Therefore, to draw one line segment, you need just two endpoints. But drawing four line segments interchangeably (from one endpoint to another) requires five endpoints. Here's why:
